M-OB-WRIKNGER- SPECIFICATION forming part or Letters Patent No. 730,125,dated June 2, 1903. Application ilecl December 18, 1902. Serial No.y135,710'. ,(N 0 model.)

To all whom t may concern:

Be it known that I, THURMAN R. HU sToN a citizen of the United States ofAmerica, residing at Omaha, in the countyA of Douglas and State ofNebraska, have invented certain new and useful Improvements in Mop-Wringers,

of which the following is such a full, clear, and

exact description as will enable others skilled in the art to which itappertains to make and use the same, reference being' had to theaccompanying drawings, forming a part hereof.

This invention relates to improvements in y that class of mop-wringerswhich are attached 1 vation and the pail vin section, and Fig. 3 is asimilar view showing the wringer-rolls adjusted to wring a mop. v

The pail Ajis of theusual or any preferred form and is `provided withthe feet B, common 'in devices of this class. f

The wringer-frame C consists of a bar bent into substantially U shapeand having short lips D at its ends, through which? fastening-4 screwsare inserted into the pail.. Additional fastening-screws are insertedthrough the angles of the frame into the pail, so that the frame isrigidly secured within the pail just below or at the upper edge of thesame. The parallel supporting side arms of the frame j are provided withnotches Ein their lower edges near their centers, and between saidnotches and the cross bar ory shoulder of the frame longitudinal slots Fare formed in the said side bars. 'Arranged between the side bars is awringer-roll`.Gr, which is supported by headed studs or trunnions H,projecting from its ends through the slots F and adapted to slide insaidslots. The studs and the roller carried thereby are normally forcedtoward the inner'ends of the slots by springs I, having their endsengaged over the studs or trunnions and depending a short distancetherefrom to a point where they are formed into coils J, from which theyare carried upward to the side bars and engaged in openings orperforations near the Vouter ends of lthe same, as shown at K. Betweenthe side bars is arranged a swinging U-shaped frame L, which is-pivotedto the said side bars near the ends of the same and depends below thesame. Awringer-roll Mis mounted between and carried by the lower ends ofthis frame,

and its trunnions N project beyond the frame, so that when the roller isswung upward to its operative position the trunnions will iinpingeagainst thesupporting-frame, andthereby limit the said upward movement.The trunnions enter the notches E in the supporting-frame, so that ,theroller is kpermitted to swing upward into the same horizontal plane asthe spring-pressed roller Gfand thereby secure the greatest possibleeiiiciency of the device. Securedto the wringer-roll-carrying frame isaleven arm or handleO, which is attached to the upper crossbaror'shoulderof the frame and projects therefrom at approximately a right angle,departing from such an angle only enough to cause itito project above,so as to 'be easily grasped when the rollis in its lowest'position..

The construction andN arrangement of the several parts being thus madeknown, it is thought the operation of the'device will be readilyvunderstood and appreciated. The pail isparti'ally filled withwater, towhich may be added soap or other cleaning agents, and the mop is droppedbetween the rolls, the normal position of which is shown in Fig. 2. Thelever or handle O is then grasped and swung upward and outward, so thatthe frame to which it is attached and the roll carried by that framewill be swung upward and inward toward the spring-pressed roll, the mopbeing compressed between the two rolls. The rolls are held thus togetherwhile the mop is being drawn from the pail, and the pressure exertedthereby eifectually squeezes the surplus water from the mop. -When themop has been withdrawn, the weightof -theframe'and the roller causes itto automatically return to its initial position. It will beobserved thatthe leverarm or handle is at one sideof the roll-carrying frame, so thatit will not interfere with the IOO of the frame. The spring-pressed rollautomatically yields to knots or other unevennesses in the mop, while itat the same time exerts av constant pressure thereon. Thesupporting-frame does not take up any needed space within the pitil andsupports the device rigidly in position, while the notches in the loweredges of the sanne permit the swinging roll to be brought into the samehorizontal plane as the spring-pressed roll7 in which position thedistance between the centers of the rolls will be reduced to a minimum,and consequently the pressure exerted by the rolls on the mop will be atthe maximum.

The device is extremely simple in its construction and is capable ofbeing nm'nufitctured very cheaply.

Having thus described my invention, what I claim, and desire to secureby Letters Pat ent, is

The improved mop-wrin ger herein described and shown consisting of :tsupporting-frame adapted to be secured within :t pail and haw ingnotches in the lower edges of its side bars, a Wringer-roll mounted insaid frame, :L spring secured t0 the said frame :md holding the saidroll normally toward the center oij' the frame, :t wringer-roll-carryingframe pivotnlly hung in the supporting-frmne at the end opposite thespring-pressed roll, :t lever projecting from the said frame, and :twringer roll mounted in and between the lower ends of seid frame andhnving its trunnions extended beyond the seid frame and adapted toengage the notches in the side bars of the supportin g-fritm e.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
